Is it possible to calculate last 1 month return on OnTester function.

 
What have you tried ?
 

I think that OnTester function apply whole of back test period ,for example from 11/1/2011 to 11/1/2016.

But I want to know both whole result and specific period result, like from 10/1/2016 to 11/1/2016.

So is there something argument to specify the period in OnTester function.

 

double OnTester()

{

double ret = 0.0;

double ret = TesterStatistics(STAT_PROFIT);  ← It will show whole back test period's profit but I want to know last 1 month profit.

return(ret);

Yes you have to calculate it, see the link provided by WHRoeder.
